My TV doesn't have a picture or displays a NO SIGNAL message

    There are many reasons your TV may not display a picture or receive a signal. This information is provided to help you identify the cause and resolve the issue.

    Note: Check if your TV operates normally after completing each step. Refer to the supplied manuals for model-specific information.

    1. If your TV is on and connected to satellite receiver, cable box, or another video device (DVD, Blu-ray Disc™ player), make sure the connected device is turned on and not in standby mode.
    2. Make sure your TV input is properly set to the correct input device. Additional information is provided for switching video inputs on your TV.

      Note: Some older equipment may use a coax cable connection directly to your TV using the built-in tuner set to a base channel of 3 or 4. This setup is rarely use and was a common setup with a VCR. After your TV displays a signal, use the remote control of the connected device to display the video.

    3. Check the cable connections between the TV and your video device or receiver.
    4. Change the channel or try a different input device or movie.
    5. The received signal may be weak.
      • If your TV uses a cable or satellite box, you may need to contact your service provider for further assistance in improving the signal strength.
      • If your TV uses an over-the-air antenna, you may need to adjust the antenna to improve the signal quality.
    6. If your TV is using the built-in tuner with direct cable or an over-the-air antenna, try rescanning for active channels. Skip this step if you are using a cable box or satellite receiver.
    7. Your TV may not display a picture if the indicator LED is blinking..
